Collybia Tuberosa
''Collybia tuberosa'', commonly known as the lentil shanklet or the appleseed coincap, is an inedible species of fungus in the family Tricholomataceae, and the type species of the genus ''Collybia''. Like the two other members of its genus, it lives on the decomposing remains of other fleshy mushrooms. The fungus produces small whitish fruit bodies with caps up to wide held by thin stems up to long. On the underside of the cap are closely spaced white gills that are broadly attached to the stem. At the base of the stem, embedded in the substrate is a small reddish-brown sclerotium that somewhat resembles an apple seed. The appearance of the sclerotium distinguishes it from the other two species of ''Collybia'', which are otherwise very similar in overall appearance. ''C. tuberosa'' is found in Europe, North America, and Japan, growing in dense clusters on species of ''Lactarius'' and ''Russula'', boletes, hydnums, and polypores.

Jean Baptiste François Pierre Bulliard
Jean Baptiste François Pierre Bulliard (also Pierre Bulliard; 24 November 1752, in Aubepierre-sur-Aube Haute-Marne – 26 September 1793, in Paris) was a French physician and botanist. Bulliard studied in Langres, where he became interested in natural history, and afterwards a position was obtained for him in the abbey in Ville-sous-la-Ferté, Clairvaux and later he moved to Paris where he study medicine. There he also practiced as a physician. He tutored the son of General :fr:Claude Dupin, Claude Dupin (1686-1769). He was an able draughtsman and also learnt to engrave. He invented a way of printing natural history plates in colour and used the method in his own publications. In 1779 he commenced a work on the poisonous plants of France. It was seized by the police on the grounds that it was a dangerous work. Bulliard's ''Dictionnaire Elémentaire de Botanique'' (1783) contributed to the spreading and consolidation of botanical terminology and the Linnaean taxonomy, Linné ...

Lactarius (fungus)
''Lactarius'' is a genus of mushroom-producing, ectomycorrhizal fungi, containing several edible species. The species of the genus, commonly known as milk-caps, are characterized by the milky fluid ("latex") they exude when cut or damaged. Like the closely related genus ''Russula'', their flesh has a distinctive brittle consistency. It is a large genus with over 500 known species, mainly distributed in the Northern hemisphere. Recently, the genus ''Lactifluus'' has been separated from ''Lactarius'' based on molecular phylogenetic evidence. Systematics and taxonomy The genus ''Lactarius'' was described by Christian Hendrik Persoon in 1797 with '' L. piperatus'' as the original type species. In 2011, '' L. torminosus'' was accepted as the new type of the genus after the splitting-off of ''Lactifluus'' as separate genus. The name "''Lactarius''" is derived from the Latin ''lac'', "milk". Placement within Russulaceae Molecular phylogenetics uncovered that, while macromorphologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ribosomal DNA
Ribosomal DNA (rDNA) is a DNA sequence that codes for ribosomal RNA. These sequences regulate transcription initiation and amplification, and contain both transcribed and non-transcribed spacer segments. In the human genome there are 5 chromosomes with nucleolus organizer regions: the acrocentric chromosomes 13 (RNR1), 14 ( RNR2), 15 ( RNR3), 21 (RNR4) and 22 (RNR5). The genes that are responsible for encoding the various sub-units of rRNA are located across multiple chromosomes in humans. But the genes that encode for rRNA are highly conserved across the domains, with only the copy numbers involved for the genes having varying numbers per species. In Bacteria, Archaea, and chloroplasts the rRNA is composed of different (smaller) units, the large (23S) ribosomal RNA, 16S ribosomal RNA and 5S rRNA. The 16S rRNA is widely used for phylogenetic studies. Eukaryotes The rRNA transcribed from the approximately 600 rDNA repeats forms the most abundant section of RNA found in cells ...

Lepista Nuda
''Clitocybe nuda'', commonly known as the wood blewit and alternately described as ''Lepista nuda'', is an edible mushroom native to Europe and North America. Described by Pierre Bulliard in 1790, it was also known as ''Tricholoma nudum'' for many years. It is found in both coniferous and deciduous woodlands. It is a fairly distinctive mushroom that is widely eaten, though there is some caution about edibility. Nevertheless, it has been cultivated in Britain, the Netherlands and France. Taxonomy and naming The French mycologist Pierre Bulliard described the wood blewit in his work ''Herbier de la France'' in 1790 as ''Agaricus nudus'', reporting that it was common in the woods all year. He wrote of two varieties: one whose gills and cap are initially light violet and mature to burgundy, while the other has vine-coloured gills that intensify in colour with age. He added that the first variety was often confused with ''Cortinarius violaceus'', though it has a "nude" cap and no spi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypsizygus Ulmarius
''Hypsizygus ulmarius'', also known as the elm oyster mushroom, and less commonly as the elm leech, elm ''Pleurotus'', is an edible fungus. It has often been confused with oyster mushrooms in the ''Pleurotus'' genus but can be differentiated easily as the gills are either not decurrent or not deeply decurrent. While not quite as common as true oyster mushrooms, they have a wide range globally in temperate forests. The mushrooms and vegetative hyphae of this species have been studied in recent years for their potential benefits to human health, and mycoremediation. Taxonomy and phylogeny The taxonomic name of ''H. ulmarius'' means both “high up” (''Hypsi''-) and “yoke” (-''zygus''), referring to where the mushroom can be found attached to its host tree. The species name refers to elm (''Ulmus'' spp.), a tree the fungus commonly grows on. This species was first described in 1791 as ''Agaricus ulmarius'' by Jean Baptiste Francois Pierre Bulliard, a French physician and bot ...

Clitocybe Connata
''Clitocybe'' is a genus of mushrooms characterized by white, off-white, buff, cream, pink, or light-yellow spores, gills running down the stem, and pale white to brown or lilac coloration. They are primarily saprotrophic, decomposing forest ground litter. There are estimated to be around 300 species in the widespread genus. ''Clitocybe'' means ''sloping head''. A few members of the genus are considered edible; many others are poisonous, containing the toxin muscarine among others. Distinguishing individual species of ''Clitocybe'' is generally prohibitively difficult to non-experts, requiring the analysis of microscopic characters. Therefore, with the exception of a few charismatic and readily identified members, ''Clitocybe'' mushrooms are rarely collected for consumption. Taxonomy ''Clitocybe'' was originally proposed by Elias Fries in 1821 as a tribe in the genus ''Agaricus''. Friedrich Staude elevated it to generic status in 1857. Recent molecular work has shown the genus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendrocollybia Racemosa
''Dendrocollybia'' is a fungal genus in the family Tricholomataceae of the order Agaricales. It is a monotypic genus, containing the single species ''Dendrocollybia racemosa'', commonly known as the branched Collybia or the branched shanklet. The somewhat rare species is found in the Northern Hemisphere, including the Pacific Northwest region of western North America, and Europe, where it is included in several Regional Red Lists. It usually grows on the decaying fruit bodies of other agarics—such as ''Lactarius'' and ''Russula''—although the host mushrooms may be decayed to the point of being difficult to recognize. ''Dendrocollybia racemosa'' fruit bodies have small pale grayish-white or grayish-brown caps up to wide, and thin stems up to long. The species is characterized by its unusual stem, which is covered with short lateral branches. The branches often produce spherical slimeheads of translucent conidiophores on their swollen tips. The conidiophores produce conidia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clitocybe Dealbata
''Clitocybe dealbata'', also known as the ivory funnel, is a small white funnel-shaped toadstool widely found in lawns, meadows and other grassy areas in Europe and North America. Also known as the sweating mushroom, it derives this name from the symptoms of poisoning. It contains potentially deadly levels of muscarine. Taxonomy and naming ''Clitocybe dealbata'' was initially described by United Kingdom, British natural history, naturalist James Sowerby in 1799 as ''Agaricus dealbatus'', its specific epithet derived from the Late Latin verb ''dealbare'' 'to whitewash', inexorably calling to mind the Biblical "whited sepulchre", that is outwardly pleasing but inwardly toxic. It gained its current genus name in 1874 when reclassified by French naturalist Claude Casimir Gillet. However, this species is often considered a synonym of ''Clitocybe rivulosa'' and according to Bon the name ''C. dealbata'' may be invalid (a :w:en:Nomen dubium, nomen dubium) as James Sowerby's defini ...

Collybia Cirrhata
''Collybia cirrhata'' is a species of fungus in the family Tricholomataceae of the order Agaricales (gilled mushrooms). The species was first described in the scientific literature in 1786, but was not validly named until 1803. Found in Europe, Northern Eurasia, and North America, it is known from temperate, boreal, and alpine or arctic habitats. It is a saprobic species that grows in clusters on the decaying or blackened remains of other mushrooms. The fruit bodies are small, with whitish convex to flattened caps up to in diameter, narrow white gills, and slender whitish stems long and up to thick. ''C. cirrhata'' can be distinguished from the other two members of ''Collybia'' by the absence of a sclerotium at the base of the stem. The mushroom, although not poisonous, is considered inedible because of its insubstantial size. Taxonomy and phylogeny The species first appeared in the scientific literature in 1786 as ''Agaricus amanitae'' by August Johann Georg Karl B ...

Collybia Cookei
''Collybia cookei'' is a species of fungus in the family Tricholomataceae, and one of three species in the genus ''Collybia''. It is known from Europe, Asia, and North America. The fungus produces fruit bodies that usually grow on the decomposing remains of other mushrooms, like ''Meripilus giganteus'', ''Inonotus hispidus'', or species of ''Russula''; occasionally fruit bodies are found on rich humus or well-decayed wood. The fungus produces small white mushrooms with caps up to in diameter, supported by thin stems that originate from a yellowish-brown sclerotium. The mushroom is difficult to distinguish from the other two species of ''Collybia'' unless an effort is made to examine the sclerotia, which is usually buried in the substrate. The edibility of the mushroom has not been determined. Taxonomy and phylogeny The species was first described in the scientific literature in 1928 as ''Collybia cirrhata'' var. ''cookei'' by the Italian mycologist Giacomo Bresadola. In a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polypore
Polypores are a group of fungi that form large fruiting bodies with pores or tubes on the underside (see Delimitation for exceptions). They are a morphological group of basidiomycetes-like gilled mushrooms and hydnoid fungi, and not all polypores are closely related to each other. Polypores are also called bracket fungi or shelf fungi, and they characteristically produce woody, shelf- or bracket-shaped or occasionally circular fruiting bodies that are called conks. Most polypores inhabit tree trunks or branches consuming the wood, but some soil-inhabiting species form mycorrhiza with trees. Polypores and the related corticioid fungi are the most important agents of wood decay, playing a very significant role in nutrient cycling and aiding carbon dioxide absorption by forest ecosystems. Over one thousand polypore species have been described to science, but a large part of the diversity is still unknown even in relatively well-studied temperate areas. Polypores are much more dive ...
